Paios Features

Powerful Software

Sweep Measurement ParameterSweeping means that your measurement is performed several times with one or two parameters being varied. Paios allows to graphically inspect the measurement data easily with a sweep slider.

Data Management and ComparisonPaios is more than a measurement tool. Paios acquires systematic data of dozens of devices and lets you compare them in the Paios software. Learn from your experiments without tedious manual processing of data with Matlab or Origin.

User-Defined SignalsDesign your own transient experiments using the Paios signal editor.A new idea for an experiment can easily be tested.

Correct RC-EffectsRC-effects are superimposed on the device current and can significantly disturb transient experiments.Paios provides routines to extract the series resistance and the geometric capacitance of the device. With these values the displacement current is calculated and the current can be corrected for the RC-effects.

Flexible Time-Resolution

Flex-res: The time resolution of the transient-measurement is varied logarithmically to obtain a very high dynamic range

Traditional measurement setups using linear time sampling can only resolve about 3 orders of magnitude in time.Paios measures up to 8 orders of magnitude in time in one shot.

This feature is especially useful for perovskite solar cells. Perovskite solar cells exhibit an extraordinarily broad dynamic range from microseconds to minutes. These time dynamics can be resolved with the feature Flex-Res of Paios.

Perovskite: Device Preconditioning

Paios can precondition the device with voltage, current or illumination and perform the experiments directly afterwards increasing reproducibility.

The response of perovskite solar cells depends on the «internal state» of the device prior to the measurement. This leads to a hysteresis in the IV curve. Use preconditioning to investigate the effect of mobile ions, ferroelectricity or deep trap sites.
